This feature class was updated from our 2012 city boundary GIS data by extracting city boundaries from Tax Area Services Section (TASS) of the California Board of Equalization 2013-2015 data release. The city boundary lines were digitized to match available county parcel base information provided from TASS in the format of CAD DWG layers and/or the Tax Rate Area (TRA) maps in PDF file. TIGER/Line Parcel data and ESRI Basemap imagery were used as reference layers. This GIS version of California City boundaries is intended for general reference, planning, and study purposes only and does not represent official property boundary determinations.
Layers in this dataset are based on combinations of the following options.
You may choose from these options to select a specific layer on the map page.
